COMBINATION INSTRUMENT.

Application filed June 1, 1918. Serial No. 237,694..

To all whom it may concern:

Be it known that I, HAROLD B. FOWLER, a citizen of the United States of America, and a resident of Waterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in Combination Instruments, of which the following is aspecification My invention relates to improvements in combination instruments, and particularly to instrumental means for shaping bodies by the cooperative action of a plurality of tools operating simultaneously, and the object of my improvement is to combine a special plurality of tools with suitable propelling and operating-means adapted to actuate them in the operationof forming special parts as of fountain-pen bodies, in a simultaneous coaction.

This object I have accomplished by the means and mechanism which is hereinafter described and claimed, and which is illustrated in the accompanying drawings, in which Figure 1 is a top plan View of said instrumental means operativelymounted in coacting mechanism for simultaneously actuating them; Figs. 2 to 5 inclusive are enlarged elevations of the four sides of the combinationinstrument proper; Figs. 6 and 7 are enlarged elevations of the opposite ends of said instrument, and Fig. 8 is an end elevation of said instrument and of parts of the coaching movable abutment for actuating the slidable tool-holder, while Figs. 9 and 10 are respectively elevations of a portion of the body operated on with one end shaped by said instrument before cutting off, and of the part so shaped after cutting ofi.

Similar numerals of reference denote corresponding parts throughout the several views.

Referring to said Fig. 1, there is therein shown a machine equipped with operatingmeans for actuating my improved combination instrument inythe shaping of orificed end-plugs 44; for a fountain-pen barrel, or other like parts. In this machine a beltwheel 32 rotates a shaft and a spring-clutch chuck or holder 30 for a tubular hard-rubber blank &3, from which my instrument forms said orificed end-plugs and then other means cuts them off. The said spring-clutch chuck is not described in construction nor Specification of Letters Patent.

action as both are well-known, and are adapted to advance the blank tube step by step in the progress of the work, as the shaped parts are cut off.

A turret 33 is mounted both rotatably and longitudinally slidably in a bearing-box 34 and is slidably non-rotatably mounted on a driven shaft carrying a cam-wheel 37 whose cam-groove receives a stud from a cam 38 on a rotatable driving cam-shaft 39, being fixedly connected to said cam-wheel which is also slidably non-rotatably mounted on the same shaft. In the end-face of said turret are a plurality of sockets to receive tools, such as a stem 35 having a tamping-head 36, and a stem 1 which has my improved combination of tools mounted thereon, said stems being removable from said sockets, but held therein by set-screws. Located on the bed of the machine between and under the said chuck and turret is atransversely movable base-plate 19 having thereon a block 29 provided with a cross-groove on which a frame is slidably adjustably mounted carrying a shearingtool holder 26 with a shearing-tool 27 removably held therein, and also carrying a pivoted abutment-block 28 having one face inclined relative to the stem 1 and the tools thereon, the inclination of said abutment-block being adjustable by means of set-screws.

A fixed rod 42 on one end of the baseplate 4:9 is adjustably pivotally connected to one extremit of a bell-crank lever 41, the latter media ly pivoted to the machineframe, and having its other extremity contacting with cam-sections on a cam-wheel 40 also mounted on said shaft 39, the said camwheel operating said lever to reciprocate the base-plate 4:9 transversely of the machineframe at suitable times during the actuation of the machine, to permit the shearing-tool 27 to approach the blank 43 to cut off a shaped part when the combination shaping instrument has performed its part of the work. Before this final stage of the work, and while the combination instrument is operating upon the blank 13, the shearing-tool holder and the abutment-block are in the positions shown in said Fig. 1.

Referring now to the detail Figs. 2 to 8 inclusive, the numeral 1 denotes an axially orificed cylindrical body, the outer end of whose orifice receives a boring-tool holder 7, containing a removable boring-tool 6 held by means of a set-screw 9.

Slidably adjustably mounted on said stem 1 is a split-block 2, held thereon by a screw 3 eompressively connecting its split parts.

The block 2 has an offset member 10 extending longitudinally relative to said stem beyond thelatter and having a transverse slotted seat for a pair of adjustable turningtools 11 and 12 placed in contact side by side longitudinally and having the diamond cutting points -24 and fixed in theiri'nner ends respectively. Adj UStlIlg-SCIBWS 18 and 14: are mounted in the member 10 and have annular flanges which enter and engage the walls of grooves in the tools 11 and 12, wherebysaid tools may be independently adjusted in "their respective relations to the work. When "so adjusted the tools are held in their adjusted positions by means of a seescrew 15 in the end of said member 10, and by means of a set-screw 16 in the side of the member.

The numeral 5 deiiotes a grooved 'body'of a bifurcated nature, whose bifurcations embrace "the'outer endof said stem 1, and are secured thereon removably and adjustably by means of a set-screw 8. This body-5 has an'oflset member 4 of rectangular form proyided on its inner face with*a raisedtransverse rib, with "inclined sides to receive a slide-rest orslida'ble tool-holder 17 transversely grooved to fit it 'slidably and having a transverse tool-holding slot with one inner wall inclined to permit of adjustments of a removably held tu'rning tool 19, the latter held in an adjusted position by means of "a set-screw 18. On the inner end of said tool 19 is fixed a diamond cutting point 20 directed toward the work. Resilient means not shown mounted between the holder 17 and the memberta'ct on the said *holder to normally hold it in its outwardly retracted positidnyieldingly. This maybe a springplate whoseouter'endis shown at-5O in Fig.

formed an end-plug centrallylongitudinally orificedat 45,'and having one end shaped 'conically outwardly at 48, 'while the remainder of its circumferential surface is shaped or stepped at 46 and 47 into diminished cylindrical parts shown However, the shaped end-plug illustrated may be varled in form, by various adjustments of the turning-tools of my device, as may be desired.

Referring again to said Fig. 1, when the action of the spring-clutch of the chuck 30 has advanced the blank 43 a step, the camactuated turret 33 advances and causes its tamping-tool to contact with the abutting end of the blank to tamp it to a correct position to be operated upon, the turret then being partially rotated to bring the blank into alinement longitudinally and axially with the boring-tool -6. The turret is then in succession cam-actuated to approachsaid blankagain, and'a's; the blank is *rapidlyTotating the boring-tool 6 penetrates 'it axially forming the central bore4t5, asshown in said Fig. -5. 'A's the turret so advances the diamond cutters 2a and '25 turn theo'utsideof the blank to form the-shouldered portions 46 and 47, while simultaneously the other diamond cutter'20 is moved inwardly gradually and progressively t'oturn the conical outer part 48 on saidblan'k,-all-these operations taking place in "coaetion and at the same time.

It will be noted that the action of the lever 41 as drivenby the-'cam-wheel 40 is such as to properly synchronize the movements bf the base-plate 49 so as to move it transversely across "the machine to cause the shearing-tool 27 to cut ofi'the finished endplug 44 at the completion of the shaping operation, and then return it to its former position. These operations thus goon's'uccessively until the whole blank is used up. The abutment-block 28 thus guides the turnin tool 19, the roller 22 preventing friction.

llaving described my invention, what I claim as new, and-desireto seeure by Letters Patent, is:

In a combination instrument, a-"stem having holding-means for "a boring-tool, a boring-tool removably mountea in said holdingmeans, members secured to said stem, 1 a turning-tool removably mounted on oneof said members, a slide-rest on theothenmernber containing a sliding tool-holder, and a turning-tool mounted removably insaid 't'oolholder,'said tools being adapted 'to ep'erate simultaneously upon andsl'iape a body p'ositioned in a certain relation thereto.
